The YAK54 is a very neatly designed EPO 3D parkflyer. With smart features such as side-flip canopy for super fast battery & wing removal, 1 nylon bolt wing brace and unique rudder hinge system. This YAK54 doesnt borrow hinges or horns from the parts bin, its all totally new, resulting in a plane comprised of parts that work together better, reducing weight, increasing strength and ultimately making it a more enjoyable plane to fly and work with. Because of its weight, the YAK54 only needs a very economic motor system, the 2408 sized brushlessoutrunner gives more than enough power on a 2S 1,000mAh battery. You dont need to buy expensive batteries to enjoy this plane, 20C is all thats needed! The large control surfaces and quality included servos make this very 3D capable. Wing moulding and fuse fit together perfectly with unique servo locations and you wont find any ice-cream container cowling here, its all EPO!
This is a well designed and totally new 3D parkflyer that wont dissapoint even hard core 3D pilots. Its scale details visiually appeal and are backed up by its flying ability!
what about weight reduction ? ex. - removing the ballast and cutting out some epo foam from the inside ? will it help with a combination of 800mah-64gramm battery?
Hi Asaac. Take a sharp needle and probe with it "gentley" on the top line of the engine cowl. The weight sits bewteen 10mm and 20mm from the front. So ye, it almost 10mm thick! thats alot of unnecessary speed, as this model is way fast enough!!!
I'm not a noob at flying but it seems that i can only fly this at just a little more than 3/4 throttle because it just falls out of the sky, it doesn't and a perfect landing is almost impossible. BTW this plane is not full 3d just semi 3d, I would also recommend gluing the wing the the main body because that seems to be a week spot....
you right about the "Hot" landings, it one of the hardest too land, however removing the nose weight does help to eaze the speed and makes that 3/4 thottle 1/2. Personally Ive had no prob's with the wing, and my first one went through hell and back. As far as 3D is concerned I think your right, but I've had some success at Prop Hangs with height for safety.
My Yak arrived today, thanks HK! Dare I say the Yak is back!
Quatered the nose to remove the weight and enlarge the batt comp for 3s 1000mah (it should slide up as much as possible.) Ripped out the servos and replaced with better quality. Nipped up all control horn mounts (these will require a little CA down the line to strenghten). Pulls 17.3 A on the Turnigy 2 in 1 with a 3s 1000mah. Set up D/R at 70 50 and 100 30. Keep the elevator at 30 or 40 or else she can be twitchy.
Awesome little flier! Looks great and shreds the park! This is my second...
Thank H.K Great bird, Great service!
After a hard life and final burial around 2 yrs ago, I've decided to revive my love affair with this little beast! Yes I've ordered another one, and after the tweaks and mods she'll give me the BUZZ once more!!! YAK Baby, Papa's waiting for you!
It does say clearly under Required: Your TX & RX
7.4V 2S 1000mah lipo battery. A TX (transmitter) is you hand held controller and RX (receiver) is the part that goes in model. So No it does not come with a controller.
I answered the same question some where else. Please the ESC (Motor Controller) has 2 wires to battery and 3 wires to motor. Also 3 little wires going to one plug that plugs into your receiver. You must have it plug in but where did you plug it. If you plugged it into the BAT then that is wrong. Plug it into channel 3. Let me know if I can help you any more PLEASE.
Can anyone help me with ESC programming of this plane? TX binded, servos works fine, but throttle do not work.
I turn on the RX, move throttle stick up to maximum, then connect battery to the ESC. The ESC beep shortly, and then keep beeping like "beep-beep-beep-beep-beep". I move throttle stick down but the ESC still keep beeping.
Any ideas how to fix this problem? Thanks in advance!
Alexey well done. It is easy to get caught. The use of ESCs have caught, a lot of older RC system OUT. Well done. Also thanks for coming back and telling us.
Yes, but the fitting needs work. I have cut out 1 inch middle part of the cockpit and the turnigy 1300 stands on the side in the very front. Trim is ok this way.
Is it a suitible plane for a trainer plane or is it for your average pilot who flies most days because i have just bought the bixler (glider) and i was going to use its 6 channel radio and then buy another battery for it.
I would say it is NOT suitable. It is prone to very severe stalls and high landing speeds. If you have experience flying fast warbirds then you should have no problem with this. The plus is that it's epo and very tough.
I also would say not.suitable for beginner. Low wing planes like this and the warbirds are much less stable than high wing "trainers". If you don't want a pure trainer then go with a J-3 CUB. Tons of detail but a very stable plane to fly. Could also go with a cesssna for the same properties. All the foamies now have tons of detail so they should be fun to have around and easy to fly.
But you mention flying most days so I would venture to say this plane would be fine for you.
Can't give you a measurement, too many variables in play. I would just say start towards the middle of the wing and move back until you get the performance you are looking for.
Hello
I need to buy new propellers for my Yak 54 which is not modified. So I need the original 3 blade propeller or 2 blade identical which also fits.
Thank you.
I very enjoyed this airplane with 9x6 2blade prop and 3S 1000 battery. I also tried use 8x6 3 blade, 10x6 2 blade (wood turnigy), it was flying enough good but it seems to me that the 9x6 prop is the most suitable - soft sound, nice pull, normal current from battery.
Cons All servos have lots of slop Wing loading is too high for good 3D Hard to balance properly with a 2s Needs a 3s but doesn't have much room
It is very scale looking but requires a decent amount of speed to avoid stalls. More of a sport plane 5 stars for looks 3 stars for 3d capabilities 1 star for HK calling this "very 3D capable"

Beautiful little plane, with great fit and finish.
Underpowered with stock prop and 2s battery. 9-6 SF prop helps somewhat.
Motor mount loose, fuse halves not fully joined.
Rx connector on ESC had loose contact
Hard to handle without Expo. Dual rates flyable but performance suffers.
Will not fly slow in level flight, landings must be hot.
See my mod to the motor mount and some flight footage here:

Fabulous looking scale model but there are a number of problems
1.poor quality servos sloppy around center
2.underpowered
3.poor flight characteristics-a handful for the most experienced!
